Front‐Back Discrimination in Free‐Field Sound Localization

Sound localization and word discrimination in reverberant environment in children with developmental dyslexia.

OBJECTIVE Compare if localization of sounds and words discrimination in reverberant environment is different between children with dyslexia and controls. METHOD We studied 30 children with dyslexia and 30 controls. Sound and word localization and discrimination was studied in five angles from left to right auditory fields (-90o, -45o, 0o, +45o, +90o), under reverberant and no-reverberant cond...

Sound localization in a small passerine bird: discrimination of azimuth as a function of head orientation and sound frequency.

Sound localization is critical to communication when signalers are distributed widely in space and when reverberations that accumulate over distance might otherwise degrade temporal patterns in vocalizations. We readdress the accuracy with which a small passerine bird, the eastern towhee, Pipilo erythrophthalmus L., is able to resolve azimuth in the field. We then report results from two-altern...

The effects of lesions of auditory cortex on discrimination of sound localization in dog.

The studies by Neff on cats (Neff et al. 1950, 1956) have demostrated that bilateral ablations of the temporal cortex produce dramatic impairments of auditory cue localization. I t was considered useful to test his results by a completely different method, namely by utilizing go-no-go differentiation to two auditory stimuli, sounding from different places in standard conditioned reflex experime...

Sound localization in the alligator.

In early tetrapods, it is assumed that the tympana were acoustically coupled through the pharynx and therefore inherently directional, acting as pressure difference receivers. The later closure of the middle ear cavity in turtles, archosaurs, and mammals is a derived condition, and would have changed the ear by decoupling the tympana. Isolation of the middle ears would then have led to selectio...
